Nothing imminent but there are a few ideas we're kicking around. Since these vehicles are automatic a 2step makes no sense, and would likely require a complimentary back end flash to work properly.

We did recently add CPI control to the Q50 JB4, but have not setup a full CPI yet for testing. This is what our Stinger CPI kit looks like: https://burgertuning.com/products/fu...f3311159&_ss=r

Looks fine but try to keep the gas pedal down 100% for those logs!

Hey terry, i have a 2018 Q60 RS with Ams intakes oil catch can and hks bov. About a week ago i got a code that popped up 0101 and found out it was the MAF sensor. Im unsure what to do i clean the sensors with MAF cleaner and it was fine until i did my most recent log which i attached below..

Please help im not sure if the connections on my jb4 harness might be loose hopefully you can help

Also if you can let me know if anything looks off in the log im currently on 91 octane amd the elevation is pretty high where my at.

Thankyou

A 2 step makes perfect sense. It's how you A) control launch rpm reliably, and more importantly B) build boost on the line which is the achilles heel of the platform without a tune.

CPI doesn't really make sense on top of the WMI kit. The WMI can simply have the nozzles changed for more flow and you don't just get the octane boost you get the cooling affect.

Just got my jb4 on the q50 running map 4 which should be 6lbs over boost on 93. What do you think of this log. I'm still trying to understand these logs.

I recently updated to firmware v9 and duplicated the default settings as shown in the photo on page 1 with map 4 selected. Not sure which settings affected my car, but throttle response was limited to the point where the car would barely pick up speed with a lot of throttle input.

Any idea what could cause this condition, specifically which setting would cause this reduced throttle response? I have the 400hp version engine.

Hi Terry, could you take a look at my logs? wondering if running Map 1 & 2 is good and if I can safely run Map 3 on the RS? I'm at a high elevation 3,500 ft and have decent 94 octane (no ethanol) gas. Thanks for your time!

2steps are used in applications where you can't load the engine. e.g. manual or DCT. In an automatic you brake boost and make much more boost off the line than you ever would using a 2step.

CPI would be used instead of WMI for customers who had E85 access.

No setting should cause that, maybe have a fault code stored? Log of issue?

Map2 is probably the best fit here going off the timing profile. Map3 likely too strong for it.

Is there a way to clear all the old logs stored on the jb4 app? Just got a new engine and don't need any of the old info anymore.

Yes, on iPhone at least. Just go to logs, and then swipe left on a log and it will show a little red box that says delete.

Do you step on it and nothing? On your JB4 set the gauges to show pedal and throttle. When this happens does your pedal go to 100 and throttle jumps to 100 then down to 26? Or throttle just never goes to 100 but stays mid20's? If so, several people are experiencing this. Still no explanation. I gotta get some logs uploaded here to show it happening. I almost exclusively drive in manual now and I do see that in 1st and 2nd my throttle rarely goes to 100.

Not sure your drag racing experience but 2 steps are used in the drag racing world with autos all the time. You're kidding yourself if you think holding the gas and the brake will make more boost on a tight factory torque converter compared to sending unburnt fuel out the cylinder to the turbo. I get it. You don't think it's worth it....so I'm making one. Already have interest from others and have the SPICE model working. It would be easy to integrate with a JB4 firmware update.

Not Terry, but I think your log looks fine. Timing (Ign1) drops a little low at mid-range. You may want to back off a bit, maybe top out at the 4.2 on your map6. Also think you don't need to taper quite so much on the high end. So maybe look to add .5 to your values after 6k RPM. The stock JB4 maps taper but to less extent. You also would gain a little at high end with fuel wires. If you have them hook them up.

Thanks for the feedback JCB. Any thoughts on why my ECU psi tops out at 12.7? I never seem to see 14.7 or close.

I'm a non RS so focus mainly on the total boost numbers. I looked at a few logs on this site from the near past and RS models seem to be peaking out at 13.1PSI in the high 4000 rpm range. Yours is just shy of that. I did notice that your pedal input is not at 100. That is unusual when throttle is showing 100 for an extended pull like you posted. Maybe the pedal input is holding back the boost slightly on yours? Do you have any other logs to see if that is a consistent issue or a one time aberration?

Here's an earlier log where you can see I'm getting 99% pedal in the power range.

Yeah this log you peak out at 13.1PSI right as you cross 5k RPM. Not sure where the 14.7 you are looking for is coming from - is that advertised peak for an RS?.

Anyway, go back and look at logs from other RS models in the thread. I think you will find yours is performing normally. Now that you have JB4 you can focus on your total boost and dial that in.
